The offset Spectra Bass body style was innovatively designed with the gigging musician in mind. Its poplar body with distinct poplar burl top has a larger upper horn that evenly distributes weight throughout the instrument for perfect balance and playing comfort. The graphite-reinforced through-body maple neck with scarf joint creates formidable sustain, with a speed neck contour, 12"-16" compound radius bound laurel fingerboard and 24 frets for superior playability.

The SBXP IV provides a full-sonic spectrum for even the most versatile and progressive bassists. Dual passive medium-output humbucking pickups create a dynamic foundation with punch, power and note articulation. Wide-ranging tonal command comes from a two-way toggle switch for pickup coil splitting, three-band active EQ, three-way toggle variable switch, blend control and volume control with push/pull selector to bypass or engage active circuit for the 3-band EQ. The push/pull selector eliminates the risk of losing sound due to a dead battery. A quick pull on the volume knob bypasses the active circuit, making it easy to regain sound from the bass without the use of battery power.

This four-string bass also features a HiMass™ hardtail bridge that enhances sustain and improves note attack.
